FancyBox
From OpenEMR Project Wiki
FancyBox In OpenEMR
Fancybox is used in OpenEMR as a replacement for pop-up windows. popups are becoming deprecated in modern browsers, and the window.close() function used to make a popup disappear is disabled in at least one browser.
Versions
Two versions of FancyBox exist in the OpenEMR codebase.
Integrating these two versions is not a big priority, see thread: http://osdir.com/ml/fancybox/2011-12/msg00192.html .
For new code, it is preferred to use the 1.3.4 version, rather than the 1.2.6 version.
